Materials
18/8 Stainless Steel Construction
The Rambler Jr. is manufactured from premium kitchen-grade 18/8 stainless steel, providing excellent durability and long-term performance.
This material resists punctures, dents and rust while remaining easy to clean and suitable for everyday use. The robust construction helps the bottle withstand drops, bumps and the general rough treatment often associated with children's gear.
Features & Technologies
Double-Wall Vacuum Insulation
The Rambler Jr. uses YETI's double-wall vacuum insulation to help maintain cold drink temperatures for longer.
The vacuum-sealed gap between the inner and outer walls reduces heat transfer, helping keep water refreshingly cold throughout the day whether at school, on family outings or during outdoor activities.
Leakproof Straw Cap
The included colour-matched straw cap is designed to help prevent leaks when properly closed.
The integrated straw allows easy sipping while helping children stay hydrated throughout the day. When closed correctly, the cap helps reduce accidental spills inside bags, lunch boxes and vehicles.
Please note that while leakproof when closed, the straw cap is not intended for carbonated drinks or hot liquids.
Kid-Friendly Design
Designed specifically for children aged 3 years and older, the Rambler Jr. combines a compact size with simple operation.
The easy-to-use straw system encourages regular hydration while the durable construction helps withstand the demands of active everyday use.
Dishwasher Safe
Both the bottle and the straw cap are dishwasher safe for simple cleaning and maintenance.
This makes it easy to keep the bottle hygienic and ready for daily use.
Adventure-Ready Durability
Like the rest of the Rambler family, the Rambler Jr. is built to handle everyday adventures.
The tough stainless-steel construction helps protect against accidental drops and impacts, making it suitable for everything from playgrounds and classrooms to campsites and outdoor excursions.
